Cryonectes was a marine reptile that lived in the Early Jurassic seas, about 185 to 183 million years ago. It was a pliosaur, a type of plesiosaur with a big head and a short neck, built to hunt other sea creatures. Its fossils were found in Normandy, France.1 3

Cryonectes is known from a partial skull, lower jaw, and ten vertebrae, which were collected in the 1980s from a quarry in France.1

Its skull is about 47 centimeters (19 inches) long, making it a moderate-sized pliosaurid.1

The name Cryonectes means 'cold swimmer' because it lived during a cool period in the Early Jurassic.1

Cryonectes was a subadult when it died, as shown by its vertebrae having open growth plates.1

Its snout is very long, and the lower jaw has a long symphysis (where the two halves meet) with seven tooth positions.1

Scientists think Cryonectes is one of the earliest pliosaurids, helping to show that pliosaurids evolved earlier than previously thought.2
